If you think you're going to be able to wait 12 years for your 9 year old, then she's going to teach you a few things.
I fully expect my 8 year old will be asking to go out on dates when she's about 14. My plan so far, is that when she turns 14, she can go out in large groups to things like the movies. Boys and girls can bot be there, but it can't be just boys, and it can't be just her and one other.
When she gets her full, unrestricted liscence at about 17, she can go on boy/girl dates, IF she drives. I don't trust guys to bring her home when she's supposed to, so if I tell her she has to drive, then any lateness is all on her shoulders. She'll have a full tank of gas, and I'll check the milage.
If she's late once, then she won't go out with anyone for 2 weeks. If she's late twice, she won't be going out with anyone for a month, and if she's late a 3rd time, she has no car, and no dating privlages.
Ok, it's a bit harsh, but I'll still be a young mom. I remember VIVIDLY what happens on dates, and how it feels to go out, and think you can do things and get away with them.
I also have cousins, sisters, and neices who are going/will be going through all this. My husbands cousin just turned 17, and we have gotten stories out of her. She sneaks out all the time, has been busted with drugs, smokes, drinks, etc. And she's actually quite a good kid. She graduated in December, a year and a half early. She holds two part time jobs for her own spending money. She bought her car, and pays the insurance on it.
Moral of that story? No matter how 'good' a kid is, it doesn't mean they will always do the right thing, or that they even understand that what they are doing is wrong.
So, my kids will definatly be grilled regularly. Not because I don't trust them, but because I don't trust society, or the feelings that happen when you try something new.
